Picture backups

My S4 Mini was forever backing up my pictures, which is great, but I really don't know to where! The phone broke and was sent for repair, got it back yesterday and it was swiped clean. New motherboard. Does anyone have any idea where the photos could have gone? So sad...

Welcome to Android Central! How do you know it was backing up pictures? Was it backing up to Google+, or was it some Kies thing? Try checking your Google+ Photos page on the web, and look for an Auto Backup folder.
